Features
- Ports can be fully configured from software as a) 4x independent 3G-SDI/ASI, b) 1x 12G-SDI with ASI/SDI side channel, or c) quad-link 4K.
- External synchronization of SDI outputs with analogue genlock port that accepts bi- and tri-level sync signals.
- The smart architecture of the DTA-2174B enables a cost-effective hardware design, unrivaled by other cards in the market.
Applications
- Software-based 4K decoder and/or encoder with 12G-SDI or quad-link 3G-SDI interfacing.
- 4K decoder with 12G-SDI and downscaled triply-buffered HD/3G-SDI monitoring output.
-
Multi-port SDI and/or ASI applications, e.g.:
- Live production mixers;
- Transport-stream multiplexers;
- SDI multi viewers;
- Multi-channel transcoding to/from IP.
Block Diagram
The DTA-2174B features four send/receive channels consisting of cable equalizer/driver, Matrix API logic and high-performance DMA controller. Some typical configurations are shown below.
Please refer to the Firmware Variants application note (see "Documentation pane on the left) for an in-depth description of the various configuration options.
Four independent 3G-SDI/ASI channels
Each channel can be configured (i) as input or output, and (ii) as ASI or SDI (SD, HD or 3G).
Quad-link 4K input or output
In these configurations a single 4K stream is sent to or received from the software. The firmware converts the 4K signal to/from a SMPTE 425-5 quad-link signal.
12G-SDI with ASI/SDI side channel
A main 12G-SDI input or output channel with a "side channel" that can be used independently for e.g. downscaled SDI output (up to 3G-SDI), or an ASI input or output. If the side channel is an output, it can be triply-buffered on ports 2, 3 and 4.
DekTec Matrix API® 2.0
The Matrix-API framework decodes incoming SDI data into pixels (in a programmable format), audio samples and ANC data structures. When a new frame has been received, the framework calls a user-supplied "frame-processor callback" for processing of the data. The user callback can create output video, audio and ANC data, which is encoded by the framework into SDI frames.
Synchronization of multiple input streams is straightforward: The video/audio/anc data of all SDI frames supplied to the callback function have the same arrival time by definition. Past frames can be accessed by an integer frame index. The framework ensures that if frames from different input ports have the same frame index, they have entered the system at the same time instance.
